Question

Which elements have the highest electronegativities on the periodic table?

Answer 1

Elements that have the highest electronegativities on the periodic table:

• Elements of the halogen group, such as $\mathrm{F}$, $\mathrm{Cl}$, and $\mathrm{Br}$, have relatively high electronegativities.
• Fluorine is the most electronegative element, with a value of $4.0$.
• Fluorine is flanked by $\mathrm{N}$ and $\mathrm{O}$, both of which have strong electronegativities.
• Electronegativity is the degree to which elements 'desire' electrons.
• To put it simply, the stronger the electronegativity of an element, the closer it is to Fluorine.
